DAY COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF OHIO EGG WHIP AND THE LIKE Application filed July 27, 1928.

This invention relates to whips for'beating eggs, cake batter and substances of like'consistency and has for an object the I ovision of a whip which is exceptionally e cient.

Another object is to provide a wire cagetype of whip, for the purpose stated, which is free from disadvantages heretofore lnherent in this type of device.

Another object is to provide a structure 1o which will permit of the assembly of a greater number of wiresthan was heretofore practical in devices of this kind. l

These and other objects are attained by the means described herein and disclosed in the 15 accompanying drawing, in which:

Fig. 1 represents a composlte of two vertical sections taken through the device yof the invention, the left-hand side being taken on line A-X as indicated in the several remain- 23 ing figures; the right-hand side representing a similar view taken on line B-X.

Fig. 2 is an inverted plan view of a member forming a detail of the invention.

Fig. 3 is an inverted plan view of a part C5 forming a detail of the device shown 1n Fig. 1.

Fig. 4 is an inverted plan View of another part forming a detail of the device in Fig. 1.

The device of the invention comprises a plurality of bent or formed steel Wires arranged in a somewhat circular form and having their free opposite endsarranged between plates Which are supported on a common shaft. The outstanding advantage of the present structure is its unusual strength which is due to the manner of retaining the wires with none of the strained or previously formed portions exposed without the retaining means. In the present embodiment there is provided a socket member 8 having a bore 9 for receiving the rotatable shaft of a mixing machine. The body of the socket 8 may have a bayonet slot 10 for mounting the socket on such shaft. The socket is preferably formed with an inverted truncated conical shield 11 which is spread at its lower end to form a plate 12. The flange 1l and plate 12 are connected by a reduced inte ral neck 13 through which a reduced bore 14 extends 5 in axial alignment with the boreu9.

The plate 12 has an annular concentric row or ring of perforations 15 and a peripheral notch 16 for each of the perforations 16. These are all concentric With the downwardly depending hub 17 of the integral neck 13.

center connecting rod 18 is received in the t threaded portion 19 of the bore 14 and serves oval face 22 and a shoulder 23 which terminates in a peripheral boss 24. The peripheral boss 24 has a series of gr0oves'25 extending across it corresponding in number and relative spacing with the perforations 15 and notches 16 in the plate 12. The bottom clamping plate 26 has a flat face for abutment with the flat face 21 of plate 20 and these plates are of substantially similar shape and size so that they are readily mounted one on the other by means of screws 28 extending through coinciding perforations in the plates. The plate 26 is provided with a channel 29 parallel with the periphery of the plate and coinciding with the channel 30 formed adjacent the shoulder 23 in plate 20. As may be best seen in Fig. 4, the bottom of plate 26 has substantially a reversed S- shaped depending vertical vane 31 which has its maximum height at the center and tapers down in each direction to the level of the plate.

As may be noted from Figs. 2 and 3, the perforations and notches in the plate 12 and the grooves in the clamp plate 20 are equal in number around the peripheries of those plates and are equally spaced on the individual plates. A number of similar beater Wires 32 corresponding to the number of perforations and grooves are provided and are adapted to have their opposite ends-secured on the plate 12 and between plates 20 and 26 respectively. Each of these wires 32 has.

at its one end an angularly turned portion or lug 33 made by bending the 'wire at substantially right-angles to itself and, at its other end a knob or shoulder '34 made by upsetperiphery ting, swaging 'or by other means, the end of the Wire. n This latter knob is adapted to seat in the channel formed between the c0- inciding grooves 29 and 30 in the plates and a short portion 35 of the wire lies in a selected one of the grooves 25 in the plate 20. The Wires are thus evenly distributed about a of plate and are retained in position y clamping the plate 26 thereover by means of the screws 28.

At the opposite ends of the wires 32, which are given an arcuate form, the lugs 33 are entered into one of in one of the notches 16. An annular clamp plate or ring 37 has perforations 38 disposed about it for receiving screws 39 which enter the threaded bosses 40 in the plate 1'2 for retaining the ends of the wires 32 in position.

The rod 18 has its opposite ends threadedly received in the neck portion 13 and the hub .ing of the plates 'and extending Athese wires conform 190 thereby effecting a predetermined spacand effecting a predetermined curving of each of the wires 32. The wires or whips 32 being of uniform length from a circular anchorage on the plate 12 are arranged at the opposite end in an oval. The uniform chosen length 0f the wires is such that at the major diameter of oval plate 20 the lower portion of to the inside of the bowl. The resultant cage-like whip is therefore not circular in plan, but is flattened at opposite sides because of the minor diameter A of plates 20 and 26.

j With the wires thus retained in position,

a very rigid whip'is provided. There is no danger of breakage of the wires because those body portions namely 35 and 36 which are retainedA at the opposite ends are sound and are in no danger of breakage which might occur if force be exerted at thebend of lug 33 or immediately adjacent the shoulder 34. The wires are preferably of noncorrosive metal, for example stainless steel or an equivalent metal and -because of their small diameter, may be propelled through a mass of substance to be mixed or beaten with great ease and with a minimum of power. The advantages resulting from the strength, shape and structure of the whips will be apparent in the ensuing description of its operation.

Whips of this the socket portion type are machine driven, 8 being attachedl to the depending shaft of a mixer in any ofthe well known ways e. g. by a pin and bayonet slot connection. The substance to be mixed or. beaten is placed in a deep mixing bowl and the whip or beater and its actuating shaft (not shown) are lowered until the vane 31 comes in substantial contact with the bottom of the mixing bowl and the major diameter of the cage formed of the wires 32 practically scrapes the side offr the bowl. It may the perforationsl while the body portion 36 adjacent thereto rests beA noted here 4that the lower half'of the Y maximum curve of the cage or beater, in its referred form approximates the contourv of thea lower insideportion of the mixingD .rotation of the beater will bringcertain opposed pairs of the wires 32 into intermittent substantially scraping contact with the inside of the bowl while those spaced'90o from them about the circle will not so closely approach the side of the bowl'. The reverse Sshaped vane at the bottom during its rotation con-A tinously throws the lowermost or least agitated portion of the substance outwardly where it will mix with that portion of the substance which is being violently acted upon by the whips. In this way there i's no portion of the substance acted upon that is not beaten uniformly with the rest. T his is of considerable advantage over previously used wire whips wherein the wires were at their opposite ends secured at the top of the whip and the lowermost portions crossing one another on substantially the axis of the whip. Such a structure obviously limited the number of the wires which might be employed in a given beater because a relatively inactive area equal to the sum of the diameters of the wires, plus clearance, results from the crossing o-f the( wires at the bottom .of thatold type of whip. Such a mass of crossing merely drags thevmaterial with it without effecting a whipping thereof. Numerous means have been resorted to in efforts t0 improve beaters or whips, some of these including the passing o-f the individual wires through perforations in the shaft and in various other ways. The present structure however permitsof the use of any desired number of wires and each of those wires is active over substantially a uniform maximum area. Furthermore this structure together with the centrifugal vane vat the bottom results in a complete uniform and rapid mixing.

As previously explained the wires 32 are of uniform length and are anchored at one end in a circular arrangement whilethe opposite ends are anchored or retained in an oval. The resultant flattening at opposite sides of the completed whip provides heretofore unattained eiliciency and speed for the whip..

The whip is turned on its axis and moved bodily through a circumference in the mixing bowl. The axial spinning of the whip provides a momentary substantial contact betwen the whip (at its major diameter) and the bowl and a succeeding spacing of the whip (at its minor diameter) from the bowl in rapid succession so that a large volume of air is actually drawn into the substance operated on.in the bowl by a suction created thereby. This provides a highly desirable,

lightness andl fluffy consistency of finishedv 4 product in one half to one fourth the time ing a plate having an annular group of perforations therein, a central socket on the plate adapted for attachment to an actuating shaft, a rod depending from said socket portion, a clamp plate secured to the free end of the rod, a co-operating clamp plate adapted for attachment with the first mentioned clamp tti plate, said co-operating plates having between them `an internal channel of substantially elliptical form and a series of spaced transverse grooves communicating with said channel, a plurality of single wires of uniform length having shoulders disposed in said channel, the wires being retained between said co-operating plates, lugs on the opposite ends of the wires for entry into the perforations in the first mentioned plate and an annular clamping member secured to said plate and retaining the wires in position thereon.
